D9762: [Image Wallpaper] Just use Timer to determin when we're ready

[M. Vefa Bicakci]

  Hello!
  
  This commit causes a regression on my system. [1] In summary, during plasma's start-up the desktop background/wallpaper is initially displayed, but as soon as kscreen sets up the displays there are a number of flickers and the wallpaper is replaced with black background. I can reproduce this issue relatively reliably with compositing switched off.
  
  I was able to resolve this issue locally by reverting this commit on my system, and I verified that the reverted commit resolves the aforementioned regression. I found this commit by inspecting the git history.
  
  Would it be possible to revert and/or rework this commit?
  
  Thank you!
  
  [1] An x86_64 laptop with an up-to-date version of Kubuntu 18.04 with plasma-workspace 5.12.7, connected to an external display using HDMI.
